UNITED STATES PATE JOSEPH H. GRANDE, OF SALINAS, GAILIIOIRNIAv nmraremroa snrrrnm cnam ers of ice, nthe layers being se arated by hori- Vzontal partition sheets an an important feature of my invention is these separating or artition sheets.

y invention consists in whatever is described by or is included Within the terms or sco of the appended claims. i

In t e drawingpacked refrigerator crate embodying my invention; s

Fig. 2 is a section on the line 2f2 of `ig.3 isa top plan view showing the procedure in applying the packingsheetal.that,l

in effect, linefthe walls of the crate or container; Figui is tion or separator sheets. 80 The shipping box or crate, 10, shown is of cubical form w1th end, side andbottom walls and being of ordinary construction.

The vertical walls and bottom are lined or covered with liquid-proof sheets of cardboard. These sheets, 11 are of such form and number that by folding they cover the entire inner sides of the crate and the bottom. Necessarily certain of the sheets extend at riglht angles to others. The top poredges rof the crate walls and lap downv over the outer sides thereof. Afterwards, when the crate is packed, some of the to flaps are folded back over the top, as in icated in Fig, ^.3, one flap lying upon anotherv when all arefolded over.

Within the lined walls of the crate vegetables, such as heads of lettuee,L, for example, are El 50 above the o er with layers of ice. Thus a Application ma um 11., iaso. serial' No. 474,462.

a plan view of one of the 'parti-'i e sheets are carried over the topfa way effects the storage of water 1n the acked in horizontal layers one' horizontal thin la er of cracked ice", 12, is

iirstplaced in the ined bottom; then aflayer of vegetables, lettuce for example, is placed upon the layer of ice, then upon the layer of vegetables is placed another thin layer of cracked ice, and u on the latter is placed a division or partition sheet, 13, of cardboard or Eaper that extends entirely across between teside walls land is erforated by numerous V-shape slits, '14. pon the lowermost partition 'sheet is placed another layer formed of cracked ice, 12, -at the bottom and top and vegetables and this arrange-y ment is repeated until the crate is filled to the top. e

Pre erably the partition sheets are of or contain a material which makessuch sheets 'Y heat insulators, thus preventing lthe rapid Fig. 1 1s a vertical section through a absorption of moisture by t e cardboard.

The moisture taken up or absorbed by them aidsv in keeping the vegetables fresh and '75 crisp. lThe partitions being interposed between adjacent layers of ice, injurious effect of too much ice in contact with the vegetablesl is avoided. The openin sin the form of slits effect a certain contro ofthe quantity of water passing through the perforations because with an'l excessquantity of water, the material adjacent the slits will swell and tend to close up the slits so that the water will drip slowly through the slits and thus be most advantageously utilized on thevegetables. The cutting of the fibers by the slits facilitates absorption of water through the edges of the slits and thus in horizontal layers of vegetables and cracked A ice, such artitions having slit-form ,perfora-v tions of shape.

3'. A refrigerator shipping crate havin bottom and side walls w1th moisture-proc 5 linings and partitions of aper separating horizontal layers of vegeta les and cracked ice and extending betweenthe crate walls, there bein between two partitionstwo layers of ice tween which 1s a layer of vege- 1 tables and such partitions having slitform perforations.

4. A refrigerator shipping crate comprising an external container with moistureproof internal wall surfaces, horizontal lay- 15 ers of vegetables, horizontal layers of cracked `ice lying in contact with the layers of vegetables and partitions interposed between adjacent layers of cracked ice, said partitionsv having rforations of restricted 20 capacity to allow wn flow of water from melting ice in contact with vegetables.
